Where the hell is Lucifer? 'Mum' is gone, but Charlotte lives? Those answers and more!

According to a release, Welling will play Marcus Pierce, "an accomplished police lieutenant who is everything Lucifer (Tom Ellis) is not – strategic, reserved and well-respected." He'll also develop a connection with Decker, which Lucifer will be none too pleased about.

Lucifer's third season kicks off on Monday, Oct. 2 in a new time slot, 8/7c. As Season 2 of the Fox drama came to a close, Mom aka Charlotte was taken care of Lucifer, but now he’s facing an even greater challenge–finding out who kidnapped him, and why his angel wings are back.
